From Images to Orbits: A Hubble 2030s Astrometric Legacy for the M31-M33 Star Cluster Systems
Borja Anguiano, Benjamin J. Gibson, Sten Hasselquist
The most irreplaceable capability of HST in the 2030s is not only its angular resolution or its UV--optical sensitivity, but its accumulated time baseline. We recommend a Hubble Lo…
GALATEA: The 15-m Galactic Archaeology Spectroscopic Surveyor
Borja Anguiano, David Valls-Gabaud, Andrés del Pino +5
\textsc{GALATEA} (the \emph{Galactic Archaeology and Local-group Astrophysics Telescope for Extended Areas}) is a concept for a dedicated 15-m, wide-field, 10,000-fibre spectroscop…
Binarity Beyond Gaia: The case for a dedicated spectroscopic survey of binary stars
Borja Anguiano
Stellar multiplicity is a fundamental ingredient of stellar astrophysics, yet binary statistics across the Galaxy remain poorly constrained. The \emph{Gaia} mission has revolutioni…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Galactic Archaeology from the Northern Sky
Borja Anguiano, David Valls-Gabaud, Guillaume F. Thomas +7
By the 2040s--50s, facilities such as \emph{Gaia}, WEAVE, 4MOST, Rubin, \emph{Euclid}, \emph{Roman}, and the ESO ELT will have transformed our global view of the Milky Way. Yet key…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Resolved Stellar Populations Studies in M31 and its Satellites
C. Gallart, E. Fernández-Alvar, A. B. A. Queiroz +48
A 30 m class optical/near-IR telescope in the Northern Hemisphere, equipped for diffraction-limited imaging and high-resolution, multi-object spectroscopy of faint stars, would ena…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: A Low Surface Brightness Science Case
Mireia Montes, Ignacio Trujillo, David Martínez Delgado +27
The Extragalactic Low Surface Brightness (LSB, mag/arcsec) Universe represents a crucial, yet largely unseen, frontier in modern astrophysics. This faint realm…
